We have staggered sizes. Center sections on both rear wore to safety bars, requiring replacement. Fronts barely show signs of wear at all. I'm anal on PSI and alignment, and these have worn beautifully and ride/handle even better! Didn't realize they are uni-directional, so I can rotate sides. This is a 3 ton beast with 500lbs of torque and 4-wheel drive, almost always driven hard. Totally sold on these tires (especially over run-flats!), and have replaced with same. Maintained quietness throughout life (hard to imagine with this width), and makes this handle like it's on rails. Can't recommend highly enough.
